Document Summary

Smaller than prokaryotes and eukaryotes and slightly bigger than proteins. We need cell tissue cultures in order to grow viruses. Cell tissue cultures are much more expensive and more difficult to work with. We don"t know as much about viruses as we do bacteria. Viruses are not truly cells; too simple to be considered true cells. Are either dna or rna (never both) surrounded by a protein coating; extremely simple structure. Always require a host cell for them to attach to and get into so that they can borrow some of the replication machinery in order to multiply; they are too simple to do this on their own. Host cell can be any type of cell (i. e. : bacteria, human cell, animal cell, plant cell, etc. ) It is impossible to grow / culture viruses using artificial media. A virus can produce only either dna or rna and never both.
